Lexi, you are almost free of the security. The site works trough PayPal so any current accepted by PayPal can be use to donate or subscribe to the site.
The site is basically a one person operation and Susan operates the site out of a small house that she lives in. Your contributions pay for utilities and Susan's living expenses. We have a few large donations that have paid for equipment and some of the software. The remainder of the staff is unpaid and contributes their labor to the operation of the site. This allows Susan to really get a lot of bang for the buck and over the period of a day, this site could see as many as 7,000 users and guest. Very impressive for a shoe string budget.
You don't have to be a member of the site in order to make a contribution though most of the contributions are made by members. Last but not least, Donations are not required to be a member of the site. Many of our member are unable to contribute but contributions are appreciated.
